That is really the first place you need to check...

You are saying like my car was working fine from ages so i doubt it will go bad ..Another example..HDD's can die anytime..You cannot say if smthing was working will work for always...
Another thing you can check is the memory of your computer...Rum Memtest86+ - Advanced Memory Diagnostic Tool to check and see the RAM errors..

yeah, first check the PSU but also check to see if anything is overheating

Off Topic:

they are the first things to check

BTW: check out Speedfan (to help you trace any overheating)

Yup...if it's not the temperatures, then a new PSU would be where to invest some cash.

right, i have done memtest 86 for 8 hours, no errors, prime95 for 12 hours, no errors, as for speedfan, all my temperatures are 38 degrees C or lower, i dont quite know what my gfx card is running at. It doesnt feel too hot when i touch it seconds after the thing powers down completely. I even added a 12cm case fan next to the card, so i have an 80mm intake which goes to cpu and gfx, and the 120mm takes out on the side.

As for my PSu, I am getting one regardless of whether this solves the problem or not, because I just need one in general (Off topic: is the coolermaster iGREEN 600Watts any good?)

I am still getting shut downs in games I'm not sure if i can replace my
inno3d 6600 AGP cooler as its a completely different design to other ones and doesnt have the correct holes for the HSI heatsink and seperate GPu cooler
. Anyway 2 weeks I am buying an iGREEN from coolermaster 600Watt version, unless you lot think its a bad choice

I also stripped down the PC completely and hoovered all the fans and didnt find any spider webs or anything on the motherboard, also added more thermal grease to the CPu

I stopped overclocking my CPu and set all voltage settings to default or auto, still, no change. Its been fine for about 2 years and now all this is happening. Maybe someone has actually experienced this?

thanks all

I haven't seen much in the way of notice, but I did remember this review rating it pretty well. Additionally, they did a proper review (very few sites do, and they're listed in the PSU sticky), so while I've not used CoolerMaster PSU's, it looks like it's up to snuff.

A few suggested brands if you're trying to keep this on the cheap:

FSP (Fortron Source)
Sparkle (another FSP brand)
Hiper

Looking at what you have, anything 450+ from these brands should do the job and be easy on the wallet. Actually, if you find a Fortron/FSP AX400, that would be the one 400W that I'd recommend.

There's other great brands too, but I'm trying to keep it on the cheap here.

ok the iGREEN I have heard is good, but is not so good in the +5v rail section or something. Will it handle this: (What i hope my PC specs on this PC will be one day )

Athlon 64 3200+ clocked at 2.41GHz from 2.0GHz
nforce3 board
geforce 7800gs agp 512mb
3 IDE hard drives + 1 sata
2 CD/DVD drives
2048mb RAM in 4 sticks of 512s
floppy and card reader drives

I heard somewhere that 5V rail is for USB. I plan to use 6-8 USB devices like
USB modem, 2 controllers, mouse n keyboard, nokia phone usb connector, usb mic. and a usb webcam.

will the 600watt version of the iGREEN handle the usb devices and my "future upgraded" system?

THANKS

Yeah. I don't know if I'd look to run a pair of 8800GTX's in SLI with it, but excluding a beastly system upgrade, it should hold you. CPU's draw off the +12V, and the RAM and AGP draw off the +3.3V. PCIe cards and SATA drives run off the +12V as well.

so is that a yes to the above question?

Yes. The iGreen 600 will be more than enough for your needs.

orite, i have just tried unpluggin my 2nd hard drive and dvd drive so all i have connected is my main sata HDD and the fans, i still get crashes, im suspecting the graphic card, so im gna swap it, and if it works fine in mine and mine works badly in my mum n dads, we know

Yup. Definitely make sure something else isn't causing the problem. A better PSU can help, but only if your current one is the problem.

right, have replaced the thermal grease underneath my heatsink on the card, and it still shuts off. The previous thermal grease had gone pink and solid :S

I tried my mum n dads FX 5700 yesterday, and it didnt crash or anything, it was fine. I tried it for 30-40 mins pure gaming, crap perfomance due to the card, but it didn't shut off at all. I think I have found the graphic card is actually damaged.

maybe i should get an agp x1950 ... when i have a little more money and i have bought the 600watts iGREEN. I have seen the results of these cards, they are the same price as geforce 7800gs but have more pipelines and are much more powerful.
